-First: extract ace combat zero NTSC iso from your own disc
-Second: download deltapatcher, I used version 2.0.1 but version
probably don't matter that much as long as it have the ability to patch games
-Third: open deltapatcher.exe and select ace combat iso as the "Original file",
then select my patch as the "Xdelta patch". Lastly select
"Apply patch" and you are done.
Now every voice except intro is Japanese. (intro only have english voice file)
----Warning about small things:
When I was testing the undub, One time game freezed on me when I was trying mission 2,
but it never happened again? I don't know what caused it, I don't think it was
because of the patch, because it never happened again but still I wanted to warn you,
so save after every mission just in case
It looks like mission briefings have manual timing for english voices, this causes
sometimes mission to start before briefing voice done, so sometimes briefing voice
can cut abruptly. Unfortunately I couldn't fix that because tools I have used from
moddb only can change voice files and their tables but not timings.
It's not a big problem because you can read the subtitles of it.
But if I could, I would like to try to fix it.
Also cutscenes has manual timing as well, but fortunately it's rarely an issue,
because it's pretty close to jap voice timings. There is rare times that subtitles
dissapear or appear couple of seconds later than the voices rather than
at the same time. But like I said it's rarely an issue.
---Lastly I want to thank the tool creators.
-death_the_d0g for the bgm folder modding
-Andreisgl for the pac parser
---I hope you would have a good time with Ace Combat Zero!
